Definitions

  • the invention is the use of low molecular weight, highly amorphous silicic acids in combination with one or more stabilizers in cosmetic or dermatological preparations for reducing or preventing apoekrine perspiration.
  • secreted aqueous secretion There are three types of sweat glands in the skin, namely, apocrine, eccrine, and apoekrine sweat glands (Int J Cosmet Sei. 2007 Jun;
  • the eccrine sweat glands in humans are distributed practically throughout the body and can produce significant amounts of a clear, odorless secretion that is over 99% water.
  • the apocrine sweat glands occur only in the hairy body areas of the armpit and genital region and on the nipples. They produce small amounts of a milky secretion that contains proteins and lipids and is chemically neutral.
  • Sweating also known as transpiration, is an effective mechanism to release excess heat and thereby regulate body temperature.
  • the volume-rich aqueous secretion of the eccrine glands which can produce up to 2-4 liters per hour or 10-14 liters a day in adults, is used for this purpose.
  • the sweat - especially the secretion of apocrine sweat glands - is also signaled by the sense of smell. In humans, the apocrine sweat plays in particular in connection with the emotional or stress related
  • Cosmetic antiperspirants or deodorants / deodorants are used to eliminate body odor or to reduce their formation.
  • Body odor arises when the per se odorless fresh sweat by microorganisms such. Staphylococci and
  • deodorant and "antiperspirant”. Rather, especially in German-speaking countries, products for use in the armpit area are referred to as deodorants or “deodorants”, irrespective of the question of whether an antiperspirant effect is also present.
  • Antiperspirants are antiperspirants that, in contrast to the deodorants which generally prevent microbial decomposition of already formed perspiration, are said to prevent the secretion of sweat at all.
  • non-colloidal silver also shows odor neutralization (masking), influencing of bacterial metabolisms, the pure perfuming as well as the use of precursors of certain perfume components, which are converted by enzymatic reactions to fragrant substances.
  • Sweat odor consists to a large extent of branched-chain fatty acids, which are released by bacterial enzymes from odorless sweat.
  • Classic deodorizing agents counteract this by reducing the growth of bacteria.
  • the substances used for this purpose also act nonselectively against useful skin germs and can lead to skin irritations in sensitive individuals.
  • the classic antiperspirants used are, in particular, aluminum salts or aluminum / zirconium salts. These inhibit the flow of sweat by obstructing the excretory ducts of the sweat glands by precipitating them together with the skin's own proteins and thus leading to so-called plugs. Therefore, there may be a congestion of sweat within the gland.
  • Corneocytes in the sweat gland duct (Shelley WB and Hurley HJ, Acta, Derm. Venereol. (1975) 55: 241-60), or by the emergence of an ACH / AZG gel (Reiler HH and Luedders WL, in: Advances in Modern Hemisphere Publishing Company, Washington and London (1977) Vol. 4: 1-5), which is formed by neutralization in the sweat gland duct, remains open.
  • a satisfactory deodorant means the following conditions are met: 1)
  • liquid deodorants and antiperspirants solid preparations, for example powders, powder sprays, are also known and customary as intimate cleaners.
  • a disadvantage of the aluminum salts used hitherto for sweat inhibition is the currently not yet fully understood long-term toxicity.
  • Aluminum has been suspected for a long time to promote or trigger neurodegenerative diseases such as dementia, in particular Alzheimer's disease. Also, aluminum is associated with the development of breast cancer. So far, there is no verified evidence that works over the skin aluminum-containing AT agents are involved. If the skin is intact, the maximum admissible intake levels can not be achieved.
  • Al salts are short-chain silicates in the form of silicic acids, which can reliably suppress sweat formation.
  • Silica acids are the oxygen acids of silicon. The easiest
  • Polymers are sometimes referred to as meta-silicic acid (H2S1O3, [-Si (OH) 2-0-] n ). If these low-molecular-weight silicic acids continue to condense, amorphous colloids (silica sol) are formed.
  • the general empirical formula of all silicas is H2n + 2Si n 03n + i.
  • the empirical formula is often S1O2 ⁇ n H2O; However, the water is not with silicas
  • Silica the anhydride of silicic acid.
  • the salts of acids are called silicates.
  • silicic acid esters are Technically used or prepared alkali metal salts.
  • the esters of silicic acids are called silicic acid esters.
  • Silica acids are understood to have an extension of 1 to 100 nm, measured by dynamic light scattering. These low molecular weight, highly amorphous silicas are also known as low molecular weight polysilicic acids and are referred to below as NPK.
  • the silicas prepared by this method are stable only at these very low pH levels. From a pH of 3.5 condensation occurs, which is noticeable by precipitation gelation. These precipitates of high molecular weight silicic acids no longer have an AT effect. Since pH values below 3.5 are physiologically incompatible, formulations must be found in which the pH is at least 3.5 and in which there is no gelation or precipitation of amorphous colloids (silica sol).
  • a further object of the present invention was thus to develop AT agents / preparations which are suitable as a basis for cosmetic deodorants or antiperspirants and which do not have the disadvantages of the prior art. Furthermore, it was therefore an object of the invention to develop cosmetic bases for cosmetic Antritranspirantien, which are characterized by good skin compatibility.
